CodeBaseReferenceExpression Class

Represents a reference to the base class.

Namespace: System.CodeDom
Assembly: System (in system.dll)

[SerializableAttribute] 
[ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch)] 
[ComVisibleAttribute(true)] 
public class CodeBaseReferenceExpression : CodeExpression
/** @attribute SerializableAttribute() */ 
/** @attribute ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch) */ 
/** @attribute ComVisibleAttribute(true) */ 
public class CodeBaseReferenceExpression extends CodeExpression
SerializableAttribute 
ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch) 
ComVisibleAttribute(true) 
public class CodeBaseReferenceExpression extends CodeExpression
Not applicable.

CodeBaseReferenceExpression represents a reference to the base class of the current class. The base class is sometimes also known as the parent class or super class. References to the base class are commonly used when overriding a method or property in order to call the base class's implementation of that method or property. For example, an override of a ToString method that appends a string to the end of the base class's ToString method would call base.ToString() in C#.

This example demonstrates using a CodeBaseReferenceExpression to reference a base class method.

// Example method invoke expression uses CodeBaseReferenceExpression to produce 
// a base.Dispose method call
CodeMethodInvokeExpression methodInvokeExpression =                 
    
    // Creates a method invoke expression
    new CodeMethodInvokeExpression(
    
    // targetObject parameter can be a 
    // base class reference
    new CodeBaseReferenceExpression(),
    
    // Method name and method parameter arguments
    "Dispose", new CodeExpression[] {});            

// A C# code generator produces the following source code for the preceeding example code:

// base.Dispose();


// Example method invoke expression uses CodeBaseReferenceExpression
// to produce 
// a base.Dispose method call
CodeMethodInvokeExpression methodInvokeExpression =
    // Creates a method invoke expression
    new CodeMethodInvokeExpression(
    // targetObject parameter can be a 
    // base class reference
    new CodeBaseReferenceExpression(),
    // Method name and method parameter arguments
    "Dispose", new CodeExpression[]{});
// A VJ# code generator produces the following source code for the 
// preceeding example code:
// super.Dispose();
